title: Fetal elevation: a new technique for placental localization in the diagnosis of previa.
abstract: The diagnosis of previa is made with ultrasound when the placenta is seen to cover the internal os. The technique of fetal elevation is a simple procedure that facilitates visualization of the internal os and its relation to the placenta. The safety of this technique is demonstrated in a large series of patients.
